Setup: Difference between revisions

The Setup process for Cumulus is briefly mentioned in the 'readme.txt' and covered in detail in the help files. Once Cumulus is installed: Click Start, Programs, Cumulus and select the Help. Expand the Introduction section and begin reading at "Getting Started" until you have got everything working.

Remember ''if you try to change your old data later'' it probably has already been rounded and applying a single conversion factor would cause inaccuracy. For instance in rainfall you can't get back exactly to mmmillimetres to 1 decimal place from inches to 2 dp. For example, 0.01 ininches is 0.254 mmmillimetres, which rounds to 0.3 mm, but 0.02 ininches is 0.508 mm, which rounds to 0.5 mm rather than 0.6.

YouTo minimise rounding error, you need to convert the old data first into whatever unitsprecision your weather station works in (e.g. Fine Offset rainfall bucket is 0.3mm, its pressure measurement is in hPadPa (integer decaPascal), wind speed in tenths of metres/second and temperature in tenths of degrees Celsius), this may be different to how you have set its console display, and then convert into whatever future units you select for Cumulus before rounding. So devising suitable conversion tactics and applying to all old data could require hours of work.
